[0014]

FIG. 1 of the accompanying drawings illustrates an apparatus for connecting electrical connectors to conductors, particularly but not exclusively, to tabs of busbar conductors. Device 1
Comprises a spring sleeve 2 and an electrically insulating tubular shroud 3 in this preferred embodiment.

Referring to FIGS. 2 and 3 of the accompanying drawings, the spring sleeve 2 has the general construction of a parallel pipe. More specifically, the spring sleeve 2 is
It has a generally rectangular cross section, two opposite narrow walls 4 and 5 and two opposite wide walls 6 and 7. Wide wall 7
Is formed with an axial slit 8 at its center.

The spring sleeve 2 is preferably made of a resilient, electrically conductive material such as spring metal. However, the use of other spring materials to make the spring sleeve 2 can also be envisaged. Figure 3
, The slit 8 is bounded by two axially extending parallel, mutually facing end faces 9 and 10. From the axial corner 11 to the end face 9, the wide wall 7 is slightly deflected inward, first bent inward at a substantially right angle and then at a substantially right angle to the axial corner 12. It's turning towards. From the axial corner 12 to the end face 10, the wide wall 7 is slightly inwardly bent, first (first time) at a substantially right angle inward and then (second time) substantially. Is bent at a right angle toward the axial corner 11. As explained in the following description, this shape of the spring sleeve 2 creates a spring action for supplying pressure to the tabs and contact tails into which the spring sleeve 2 is inserted. In fact, the above-described shape of the wide wall 7 defines two axially coextensive lips with respective inner surfaces 13 and 14 for applying this pressure to the tab and the contact tail.

The insulative shroud 3 is preferably made of an electrically insulative material, for example a plastic material. The shroud 3 has a substantially rectangular cross section and comprises two opposite narrow walls 15 and 16 and wide walls 17 and 18, as shown in FIG.

The inner diameter of the shroud 3 is suitable for housing and fitting the spring sleeve 2 for an interface fit at the first end portion of the shroud 3. The shroud 3 therefore surrounds the spring sleeve 2,
A captive electrically insulating shroud to prevent accidental electrocution. Since the insulating shroud 3 is longer than the spring sleeve 2, the spring sleeve 2 is not present in the remaining second part of the shroud 3. As shown in FIG. 1, the second part of the shroud 3 is provided with two symmetrical and axially extending slots 19 each formed in the two narrow walls 15 and 16 from the center outward. There is.

As a non-limiting example, the device 1 can be used in connection with a generally flat busbar conductor 20. As shown in FIG. 4, the bus bar conductor 20 is formed with the tab 21. The tab 21 is inserted into the spring sleeve 2 through a portion of the surrounding plate 3 where the second slot is formed. When the tab 21 is inserted into the spring sleeve 2, the flat bus bar conductor 20 is simultaneously moved to the bus bar conductor 20.
It is led to two slots as shown at 19 which form a seat for use.

Finally, two parallel, substantially flat contactor tails 22 and 23 are inserted into the spring sleeve 2 opposite the busbar tabs 21 (see FIG. 5). These contact tails 22 and 23 have electrical contacts 25 described below.

It is in the opening 67 of 46.

Referring to FIG. 5, the spring sleeve 2
Form a socket member that is smaller than the contact tails 22, 23 and the tab 21. Upon insertion of the contact tails 22, 23 and the tabs 21 in the spring sleeve 2, the elasticity of the spring sleeve 2 provides a semi-permanent, high-achieving electrical contact with the contact tails 22, 23 and the busbar tabs 21. Generate at the boundary between. In this respect, contact tails 22 and 23
Are one or more bosses (FIGS. 5 and 6) configured to concentrate contact forces in a given area of the boundary between these contact tails 22, 23 and busbar tab 21.
(See axial boss 24 in FIG. 2). As seen in FIG. 4, both contact tails 22, 23 and tab 21 extend into opening 67 in PCB 46. The contact tails 22, 23 extend completely through the opening 67 to the other side of the PCB 46.

The resulting coupling produces a compressive force which establishes electrical contact between the busbar tab 21 and the contact tails 22,23. In short, the spring sleeve 2 does not necessarily carry an electric current. In fact, the spring sleeve 2 can be an electrically conductive sleeve or an electrically insulating sleeve. Those skilled in the art will appreciate that this concept operates with only one of the contact tails 22 or 23 and is located on one side of the busbar tab 21, and the dimensions of the spring sleeve 2 and the shroud 3 are therefore Please understand that it will be set up appropriately.
